auvturd [To aZZli/J homfit mag concern: I .Be-it known that I, ALFRED G. F. K Row- Brooklyn, in the county ofKings, city and State offNew York, have invented cert' in fnew and; useful Imprbvements inlType- Writing Machines, of which the following s rs i a ie Th present invention relates to a type- ,writingmachinel withwhich is combined 7 tabulating mechanism comprising a series of column stops on thecarriage adapted to be [selectivelyprojected into position to beintercepted by counter-stops on thev machine :frame. y l j T {An object of the. invention is to provide means actuatedfby' the'same key to selec ftively project the stops on the carriage and also restore the stops to inactive position.

a A further object is to provideanimproved formi ofrestoringkcam which will effect a successive?return of the projected. stops and therebyreduoe the duty placed on the camj operating'mechanism and secure a smooth and easyaction of said mechanism. p

l The counter stopsmay consist'of a series latingfsystemgthe stops being preferably in l thetorm of vertical bars sli'dable vertically keys to projectthe denominational stops into i the path of a projected column stop on the carriage; The column stops are arranged in a rowextending in the line of'the carriage travel, and are adapted tobe selectively pro jectcd or lo-wered'into the pathof the operated counter-stops; The column stops are restored".by a"key-actuated cam adapted to bedswung forward into position to lift the H stops eit-her -as the camis swung forward or during thereturnof the carriage while the cam is in. said forward position; The same key is utilized when depressed to project the column stops and when lifted above its norinal position toactuate said restoring cam.

spectively a plan and a front elevation view of the restoring cam. Figs. 4, 5, and 6 are sectional elevation views of the same, as ind cated by the lines H, 55 and 6'6 respectively on Fig. 2. Fig.7 is a perspective view of the tabulating mechanism. Fig. 8 is afsectionalelevation view showing the column stop-projecting key'depressed and a column stopxprojected. Fig. 9 is' a similar view showing the key lifted above normal position, and the restoring camin operative position. y The typekeys 1 on the key levers 2 operate through the bell cranks 3 .to swing the type bars 4 about their fulcrum 5 and bring the types 6 up to the printing point of the platen 7, which is mounted in the carriage 8, adaptedto be operated as usual'in'the ing position actuate a universalbar 9 and thereby operate escapement dogs 10 cooperating with an escapement wheel 11 which. is

"letter-feed direction by means of a spring connected to rotate with a pinion 12 in mesh with a rack 13 on a frame 14 pivoted at 15 to the carr age.

-The tabulating mechanism comprises a bank of keys 16 on the forward ends of levers 17, pivoted intermediate their ends on a fulcrum rod 18 and at their rearward ends supporting vertical rods forming a series of denominational stops 19. These rods are supported and guided in a frame 20 having a top plate 21'with a series of slots or open ings 22 at lettevspace distances apart,

through which the stops are adapted to be projected. The stops are normally supported with their upper ends substantially flush with the upper surface of the plate 21.

When a key is-depressed t 1e corresponding stop 19 is pro ected into a position to inter- .cept any projected stop of a series of column stops 23, the stops-19 thus forming counterstops for the column stops 23.

The column stops 23 are supported in a frame 24 connected to the carriage and comprising parallel rack bars 25 in which the stops 23 are vertically supported and guided. Eacl'r stop is provided in its lateral edges w th notches 26 forming seats for springactuated detents 27 whereby the stops are *yieldingly held in a normal elevated position, shown in Fig. '3', in which the lowerends of'the stops are flush with'th e lower surface of the frame 24, or in their pro ect: ed position, as shown in Fig. 8. The construction ofIthe stops and their supporting frame may be the same as that disclosed in my copending application, Serial Number 722,582, filed September 27, 1912. The column stops are adapted to be projected by means of the vertically-disposed arm or projecting device'28, which extends upward through an opening 29 in the plate 21 and has its upper end extended rearward'toa the arm 28 is connected rock arm.-31' secured to a The lower end of by'a pivot to a shaft 32. The latter isjaetuated by a key. lever 33 having a position over the stops.

fulcrum 34 and connected through a link 35 to a second rockarm36 on the shaft 32.

During the travel of the carriage the,

stops 23 are successively brought into posi-' tion directly beneath the arm 28, said stops. being Name of the '37 on the lever 33 is depressed the shaft 32 25 each a letter-space distance in adpreceding stop. When the key is rocked and the arm 28 moved downward,

' carrying with it a stop 23 to the position shown'in Fig. 8. The stop is held in this projected position by the detent 27, while the lever 33 and connected parts are restored to normal position by means of a spring 38 when the key is released. i

The column stops 23 are restored to inoperative position by means of a restoring cam 39 normallysupported in rear. of the stopsand adapted to be moved forward to operative position by means. of-- links 40 connecting the cam with the vertically-disposed rock arms 41 secured to a rock shaft 42.

the forked end 44: of whichrrestsahn arm or projection 45 of the lever 33. A coil spring 46 normally holds the cam in its rearward or inoperative ,position, with the arm 4.1 resjzing against a stop 47. When the key 37 is ifted from its normal position (Fig. 1)

The latter has-secured thereto an arm 4:3, in

to the-position shown in-Fig. 9, the projection 45 operates through the arm 43 to rock the shaft 42and swingthe arms 41, and with them the cam 39 forward to a position be- 23. By reference to math the column stops Figs. 2 to 6, it will be is somewhat irregular seen that the cam 39 in shape, the central portion being higher than the end portions,

its forward ends also having a curved outline comprising a central projecting portion 48. The purpose of'this conformation is to permit a successive actuation of the ward, rather than operating a number of stops at once. and also a gradual'lifting of eachstop. The power required to restore .f

the stops is thus materially reduced and a much smoother and easier action of the restoring key is obtained. As the cam moves orward all of the projected column stops tially :the restoration of the stops is completed by the travel ofthe carriage, which brings all ,the stops in succession into position to be. fully restored by the cam.

cam, 7 said from other of said devices when moved in the op- 'posite direction from stops by the cam as the latter moves forthat may lie in'its path are restored or parres'tored toxinoperative; position, and

Themovement of the arm 28 is limited in both directions by a pin 49 extending through a slot 50' in said arm. Thenormal position of the lever 33 is determined by the projection 45 bearing against the arm 43, the spring 38 beingtoo weak to overcome the spring 46 and swing the cam forward.

When a. tabulator key is depressed the corresponding stop 19 is projected into the path of any projected column stop or stops 23, and at the same time the carriage is released from the escapement mechanism and permitted torun forward until arrested by the engagement of'a column stop-23 with a projected counter-stop'19. The carriage is released by the following means. Each counter-stop 19 is formed with a shoulder counter-stop.

Variations may be resorted'to within the scope of the invention, improvements may be used without others. Having thus described my invention, I claim: 4
